Thus material can be carried from the lower run to the upper run without discharging and without using independent elevators or swinging buckets.

The buckets are made as shown in Fig. 5, having a bottom 2', an upright end 2" and an inclined end i Extending part way over the bucket is a cover t which when the bucket is turned as shown by dotted lines in Fig. 5, holds the material in place.

When it is wished to discharge the buckets the position of each bucket is reversed with the inclined end down, thus allowing the material to freely flow therefrom.

The mechanism I use to discharge the material is constructed as follows:-M is a carriage having wheels m adapted to traverse the track (1' and on this carriage is mounted a driving shaft N having sprocket wheels at engaging with the chains of the conveyer. In the present instance this shaft N is the driving shaft for the conveyer, being geared to a shaft N by a train of gears illustrated in Fig. 1, and on this shaft N is a rope sheave at around which passes the rope m which drives the mechanism, the rope passing around guide wheels n mounted on the carriage and around ropesheaves n n, at each end of the structure. The shaft N upon which the sheave n is mounted is driven in the present instance by a rope 00 extending to a motor. n is the usual take-up used in connection with rope driving mechanism. The conveyer E passes around a guide on under the chute M and up over the sprocket wheels n, thus turning the buckets so that their contents will readily flow into the chute M. The conveyer then rests upon rails m on the carriage M returning to the track 61'. The chute is a double chute in the present instance having passages m m the passages m directing the material to the bins, while the passages m allow the material to flow to a car or boat. A valve in the upper portion of the chutedirects the material either to one passage or the other. Connected to the carriage M is a carriage M having wheels adapted to rails a, a, mounted on the framework of the building A so that it will travel with the carriage M. Pivoted at p is a trough P, forming a continuation of the chute M. This trough can be raised or lowered by a Windlass p to which it is connected by a chain 10 In the rail or stringer a forming part of the structure A are a series of openings at and in the frame of the carriage M is an opening which aligns with any one of the openings at according to the position of the carriage M, so that a pin K passed through the opening 0 and into one of the openings (1 in the frame will lock the carriage to the frame.

I utilize the same driving mechanism to move the carriage upon the rails as is used to drive the conveyer, and when the carriage is locked by the pin K or other locking mechanism to the frame Athe driving mechanism will drive the conveyer, but when the pin K is removed the driving mechanism will operate to move the carriage using the conveyer as a rack, owing to the fact that it is much easier to move the carriage than to move the conveyer. When the carriage is moved to the position required it is again locked and motion will then be imparted to the conveyer.

While I have shown double links connecting the several pivot rods of the conveyer together single links may be used and in some instances wire or manilla rope or jointed rods may be substituted for the links and while I have shown the conveyer as free to twist in its upper run it may be guided by spiral guides, without departing from my invention.

In some instances it may be necessary to guide the conveyer in diiferent planes and in a circuitous path, depending upon the construction of the apparatus and while I have used the terms horizontal and vertical runs it will be understood that the runs may be inclined, the object of my invention being to connect the upper and lower runs in such a manner that the buckets assume the same position on the upper run as they do on the lower run.

I claim as my invention 1. The combination of a conveying apparatus, buckets thereon for the material, said buckets being fixed in relation to the chain, the conveyer being twisted between the upper and lower planes so that the buckets will assume the same position in the upper plane as they assume in the lower plane, substantially as described.

2. The combination in conveying apparatus, of the structure having bins, a trough open at the bottom, an endless conveyer passing around said structure and under the trough, fixed buckets on the conveyer, wheels over which the conveyer passes, said conveyer adapted to receive material on its lower run from the trough and deliver material from its upper run and twisted in its vertical run so that the pockets or buckets will assume the same position on the upper run as they do on the lower run, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JAMES M. DODGE.
